First: Who can read exactly is a clear advantage. The jumps between the rings (26- 30; 52- 55), the individual rings that are unexpected but well made and screwed appropriately. My problem is actually unable to read well. So I assumed that I could screw my 28mm with a 58 mm diameter in it. Wrong, is not namely without any additional rings. An for the process is not so stupid as to disappear by a faraway filter image details even with RAW. I opted for the very favorable variant because of the reviews and the price will keep this aufjeden case and determine with more intermediate rings.
As a little tip I can say for the purchase decision that the individual rings are as follows: 26-30, 30-37, 37-43, 43-52, 52-55, etc. But since I mostly just the have that between all other numbers are, I organize my right to, and then it works well. Snagging the thread I had not previously, rather that I did not get down on each other. However, you have the hang of quickly and get some fun with the money saved for the filter 100e of sizes.
